WEYMOUTH - Fire officials say a Broad Street man safely escaped a two-alarm fire at his home with his dog and cat Monday evening.

Investigator are still trying to determine what caused the blaze at 303 Broad Street, but the Weymouth Fire Department said the fire does not appear suspicious. Damage to the home is estimated at between $100,000 and $200,000.

The department said a passerby noticed that the house was on fire and knocked on the door to alert the homeowner, who was inside with his dog and cat. Firefighters arrived around 7:20 p.m. and found flames in the rear of the house.

Firefighters from Quincy, Braintree and Hingham joined crews from Weymouth to fight the fire. One firefighter was reported injured.

Ashley Studley, a spokeswoman for the American Red Cross of Eastern Massachusetts, said the agency had responded to the fire and provided two adults and one dog with food, clothing and toiletries. She said the residents were also put up in a hotel.
